What are an Industrial Blower, Type & Applications?
An industrial blower is a device that enhances the air flow effectively and efficiently using an electric motor, impeller, and airfoils enclosed in a tightly sealed housing. The purpose and function of industrial blowers is to increase airflow and remove contaminants, dust, dirt, and particulate matter. They are highly technical devices designed to produce higher pressure than a fan.
The types of Industrial blowers are centrifugal, multi stage centrifugal, axial, and positive displacement. Centrifugal blowers have a gear system and have a single or multiple stage construction. Axial industrial blower models are simpler to household fans with a central shaft that has blades attached while positive displacement blowers have rotor geometry.
The classification of industrial blowers is based on the direction of the air flow with extruder blowers and axial blowers being the two categories. A centrifugal blower uses centrifugal flow and force while an axial blower uses axial movement.
Types of Industrial Blowers
Industrial blowers are an essential part of any type of production or manufacturing operation to increase airflow and create positive air pressure. Present day industrial blowers were developed in the middle of the first industrial revolution as an air pump for internal combustion engines. The simple design of these initial designs included a motor, shaft, and impeller blades.
Industrial blowers have progressed and advanced into a wide variety of types, uses, designs, and applications to assist in the performance of industrial jobs and help in making work faster, easier, and safer. The modern industrial blower is used in processes to create a steady and strong flow of air or gas.
Though there is a wide assortment of types of industrial blowers, there are a few that are commonly used because of their endurance, reliability, and are flexible enough to adapt to a variety of conditions. They make it possible for large scale production work to be completed efficiently, reliably, quickly, and effectively.
PURPOSES OF INDUSTRIAL BLOWERS
The range of what industrial blowers can do is extensive. They pose a lot of benefits to most manufacturing facilities that produce consumer goods on a large scale, quickly, and efficiently, via an assembly line of machines and workers.
Some of the more basic needs that industrial blowers can meet with ease include exhausting, cooling, drying, ventilating, aspirating, and conveying. They can exhaust hot or cold air, dust, airborne toxins, or chemicals. On the other hand, they can also supply hot or cold air into any given structure or room.
Industrial blowers can also cool or dry different goods in a very short amount of time. They can ventilate any space for hours on end, providing a cool and comfortable temperature for the workers involved. They can also convey and move around goods from one station to another, or from in the factory to outside of it.
Industrial Blower Applications
Industrial blowers are used in operations and applications where the flow of gas or air is necessary such as conveying systems, ventilation, cooling, aspiration, and exhaust systems. The many types and varieties of blowers are designed to perform important and unique functions that are required by specific applications. This can be seen in the difference between blowers that is used for ventilating a manufacturing plant from one used to provide air circulation for a nursery.
The differentiation between blowers is determined by the type of blower, flow capacity, dimensions, operating pressure, design, and electrical rating. The many types of blowers are used for cooling, drying, dust control, and fluid bed aerators.
Air Handling:
Single Inlet blowers provide high and even airflow through the ductwork of a building. Air movement is achieved by large angle blades connected to the hub of the blower.
Fume Extraction:
A wide variety of industrial processes produce fumes, smoke, and chemicals that have to be removed from the air. The fumes and other contaminants are removed by scrubbers or points of emission. This is normally achieved through the use of a system of blowers and fans.
Forward curved blowers are a part of a whole system that is designed with a large capacity filtration system. The 99% efficiency of the system guarantees that all harmful odours, contaminants, and gas fumes have been removed.
Exhausting:
In small and enclosed workspaces where paint and vapours accumulate, industrial blowers serve the purpose of removing and filtering the fumes and vapours to keep the air clean. Since some of the chemicals in these applications can be combustible, exhaust industrial blowers have to be spark resistant.
Cooling:
Cooling industrial fans are referred to as fluid displacers due to the fact that they displace air in one location to move it to another location through the use of rotating blades. The purpose of cooling fans is to blow in cold air and drive out hot air, which gives them the name of industrial cooling blowers.
Blow-Off:
In the manufacturing process, parts that need to be painted normally go through some form of cooling and cleaning process that can involve water, specs of dust, granules, or other forms of abrasive materials. Before the parts can be painted, the particulate matter has to be removed by the forceful application of streams of air, which is provided by an industrial blower.
Blow Molding blowers provide a sufficient amount of force and power to remove water vapor from cooling operations or matter that accumulates on parts prior to their being painted. Pressure blowers for this purpose are made of materials to create the necessary pressure and drive to eliminate and clean parts.
Benefits of Industrial Blowers
Air and gas movement, filtration, and cleaning and removal have become a vital part of a wide array of industries as a central part of their production processes. Industrial blowers have become a vital and necessary part of these operations and have been found to perform above and beyond their expected functions.
All manufacturers that use industrial blowers have found them to be resilient and reliable pieces of equipment. Their well designed motors, fans, and mountings have more than proven their value and importance.
The elimination of air pollution, smoke, and unpleasant smells by industrial blowers produce a healthy and pleasant work environment. Industrial blowers minimize heat and humidity and come in a variety of functionalities and styles.
